FIELD: railway transport; locomotives. ^ SUBSTANCE: proposed locomotive has body, running gear, diesel engine with supercharging compressor, fuel-geed system, motor-compressor, air intake, air clearance, noise silencers, air bypass pipelines, exhaust device with flat reactive nozzle, ejector and clamshell thrust reverser, brake system with air reservoirs, pipelines, valves, brake shoes, traction system with energomechanical unit including engines starting system, engine automatic control system and gear train. Energomechanical unit is installed in body or on roof of locomotive and it includes additionally shaft provided with front and tail piece and traction fan with pressure ratio from 1.2 to 1.5. Engines are interconnected by shafts and connected through gear train with tail piece or front nose of traction fan shaft. Space after traction fan is connected to exhaust device and is connected by air bypass pipelines with inlet of supercharging compressor and with outlet of compressor of motor-compressor. Section of nozzle exit is made with width to height ratio within 0.20 and 0.60. Flaps of thrust reverser in idling position are located behind outer surface of ejector. Axle of reverser flap turning into working position is square to axle of traction fan in vertical position. Brake system is of combination type reactive and parking part of shoe type. Air reservoirs of brake system are connected by pipelines through check valves with outlet of compressor of motor-compressor and are furnished with working valves and brake reactive nozzles. Pipeline of brake system is made for connection to air main line of train brake system. ^ EFFECT: improved reliability of traction and brake systems of locomotive, reduced noise level in motor. ^ 4 dwg |
